Feelings are a consequence of the events of your day. Working quietly beneath the radar of rational thought, feelings can last a moment or a lifetime. Feelings represent your honest response to the events at hand. They are a gateway to understanding your character more deeply - appreciating what really matters to you and what makes you feel alive.
Here are a diversity of perspectives from the movies about feelings.
"You can't miss what you've never had."
"For each ecstatic instant we must in anguish pay."
"Worrying means you suffer twice."
"People are easiest to read when they're hurting."
"It is more difficult to pretend that you do have feelings when you don't than to pretend you don't have feelings when you do."
"We don't have the luxury of deciding when and where we want to care about something."
"I keep the emotions real. That's why it works."
"Give someone the power of prophesy, and they may live in fear of the future."
"That sense of disappointment and longing can get in the way of a mission."
"That's how it starts, the fever, the rage, the feeling of powerlessness. It turns good men cruel."
